i COMBINED FOUNTAIN .AND EVAPORATOR.

p Speccationof Letters Patent No. 8,232, dated July 22, `1851.`

` this specification.`

- apartments or chambers having a continuous.

Figure 1 represents an elevation of the fountain evaporator. Fig. 2 is a plan or top view of ditto. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. t isa horizontal section on the line 2, 2, of Fig. 1.'

The same letters of reference indicate the same parts on the several figures.

The nature of my `invention consists in constructing a vase or other like article tobe used in connectionA with a stove,4`with two as well as a periodical communication with each other, by which the upper apart-ment is kept supplied with water for evaporation,- the continuous communication of the lower with the upper apartment being e'ected by the pressure of steam generated in the lower chamber, upon the surface of the water therein and force it up through the tube into the `upper apartment,and theperiodical coml and operation.

i A represents a vase made of any desired configuration, proportions, and material.

B is the upper apartment made in the form of basin to receive the water forevaporation.

C isthe lower chamber or apartment made steam and water t-ight except its communication with the upper apartment,-for containing water for` the two fold purpose of generating steam and supplying the upper `apartmentwith the Huid. y

D is a tubeiprovided with `a screw nut E near themiddle of itslength which` fits a female screw thread formed in the `bottom of the `upper apart-ment by which it is confined in a vertical position and through which the continuous communication is ef-` fected. This tube extends within about a quarter of an .inch of the bottom of the lower chamber C, and above the bottom of the upper apartment B, a suitable distance and is then curved in -the manner of a soda i vided with an india rubber or.` other valve H on its underside secured by a pin so as to allow it to open and close. Through this screw nut E the periodical communication of the upper with the lower chamber is effected. I,'is a horizontal partitionnear the underside of thebottom of the upper apartment provided with openings corresponding with the tube D, and valve nut F, and partly servesas the top of the lower` chamber for the purpose of relieving the bottom of the upper apartment from the pressure of the steam in the lower chamber.

y perationz The lower chamber C, being filled about two-thirds with water, through the opening of the screw nut E o f the tube D which is then inserted and secured therein, thevase :A is placed upon the stove and as soon as the water is heated and a sufficient quantity of steam is generated to produce the required pressure upon the surface of the water and to keep the valve H, closed it will be forced up throughthe tube D in a continuous stream until the water is so far eX- pelled from the lower chamber C, asto get below the end of the tube D. At this moment the steam in the chamberC will be permitted to escape through the tube D, and the pressure against the valve H in the lower chamber thereby relieved; when the pressure of the water in the upper apartment B and so on until the water shall have evaporated. This vase serves as an ornamental fountain and vaporizer.

Having thus described my invention and improvement of a self-supplying evaporating fountain, what I claim therein as new and desire to secure by Letters Patent, is`

Constructing a vase or other like article with two apartments or chambers B, C, having a continuous as well as a periodical communication with each other7 by which it is rendered a self supplying evaporating fountain, the continuous communication of the lower chamber C, with the upper apart-ment B or evaporator being eected by the pressure of steam upon the surface of the water in the lower chamber, and the periodical communication by means of the valve I-I secured in the screw nut E which will be opened by the pressure of the accumulated water in the upper apartment when relieved of the pressure of the steam in the lower chamber, as fully described and represented.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
